4.1. What are the Features Specific to Pediatric Patients?
Pediatric Differences in Emergency Settings
There are specific differences between children and adults to be considered in emergency settings.
Children are at a disproportionately increased risk for different reasons:
High respiratory rate: Children are more vulnerable to aerosolized agents, chemicals, carbon monoxide, etc.
Less fluid reserve: Children are more susceptible to dehydration.
Less circulating volume: Smaller amounts of blood loss can lead to hypovolemic shock.
Developmental vulnerabilities: Infants and toddlers are less able to escape a disaster; they cannot follow directions or make immediate choices.
Anatomic and Physiologic Differences
Prominent occiput: Flexion of the neck on spine boards.
Increased amount of secretions: May require more suctioning.
Infants <3 months are obligate nose breathers: Susceptible to anatomic obstruction and infections.
Relatively larger tongue compared with mandible: May make use of bagvalve-mask or intubation difficult.
Large adenoids: Bleeding is common, especially with nasal intubations.
Flexible omega-shaped epiglottis, with anterior location: Intubation and visualization of the larynx require lifting the epiglottis with a straight blade.
Smaller diameter of the subglottic region until about age 8; therefore, noncuffed endotracheal tubes (ETTs) are used until ~8 years of age to avoid cuff trauma.
